A three-form field, i.e., an antisymmetric rank-three tensor field, can generically appear in many fundamental theories trying to unify the General Relativity and Quantum Field Theory. For example, in the 10-dimensional Type-IIA superstring and supergravity theory, a 3-form field occurs as an important constituent in the Ramond-Ramond sector [1]}, [2]}, [3]}. Furthermore, in the recently proposed Hyper-Unified Field Theory (HUFT) [4]}, [5]}, [6]}, [7]}, [8]}, [9]}, [10]}, such a 3-form field is naturally identified as a part of the spin gauge field in this 19-dimensional theory. By compactifying these theories into our mundane 4-dimensional spacetime, we expect that a 3-form field \(\Omega \)  is left and potentially generates new observable effects [11]}.
